Description
Technical field
The invention belongs to natural energy resources comprehensive utilization technique field, relate to when extracting single flow water source (rivers water, municipal sewage, lake water, underground water, seawater etc.) a kind of solid-liquid separating method of fluid-bed heat exchanger technology as low level heat energy or cooling water.
Background technology
The utilization of single flow water source (rivers water, municipal sewage, lake water, underground water, seawater etc.) Cooling and Heat Source is with saving freshwater resources in short supply day by day, for new field is opened up in using energy source, for comprehensive full use water resource provides a new thinking.And these Cooling and Heat Source why do not have large tracts of land to use and popularization mainly is because its water quality is relatively poor, dirt stops up water pump and heat exchanger often in actual motion, two patents of CN200410020630.1 that the applicant obtains and CN200420031799.2 for this reason, adopt the automatic back-washing device that big dirty foreign material are removed, alleviated the blockage problem of dirt to a great extent to water pump and heat exchanger, but above-mentioned two patent deficiencies are still to contain small-sized particle and dirt in its single flow water source after handling, the single flow water source that enters heat exchanger does not still satisfy national standard, heat exchange property is still not high, dirt still occurs and increase even blockage problem after the operation long period.
At the present main method of dirt blockage problem is to adopt 2.5-3m/s high flow rate, glueballs to clean, clean automatically methods such as little brush and fluid-bed heat exchanger technology.Can suppress gathering of dirt though increase the flow velocity method, because the increase of flow velocity causes a large amount of pumps consumptions, itself and energy-conservation original intention are disagreed; Glueballs cleans and cleans little brush automatically owing to reason results of use such as technology and bad, thereby more employing overseas equipments and cause bigger investment.At the not high problem of single flow water source heat exchange property, mainly be at present that the area that strengthens heat exchanger solves, but will increase the investment of system like this.The fluid-bed heat exchanger technology has enhanced heat exchange and the dual-use function that takes out stains, promptly can overcome the dirt obstruction problem and can improve heat exchange efficiency again, solve the problem that heat exchange area increases, but the solid-liquid separator in the fluid-bed heat exchanger technology need adopt power-equipment to carry out Separation of Solid and Liquid at present, need to consume extra power, this and energy-conservation original intention are disagreed; And it can't be separated solids fully.
Summary of the invention
The object of the invention is to overcome the deficiency that above-mentioned prior art exists, shortcomings such as dirty foreign material obstruction heat exchanger during thoroughly solution single flow water source low level Cooling and Heat Source is utilized and heat exchange property are bad provide a kind of method that extra power just can be separated fluid bed heat transmission equipment solids automatically fully that do not consume.This invention is in the outlet of fluidized bed heat exchanger equipment single flow water source motorless gravitational settling formula solid-liquid separator to be installed, on the basis that does not increase extra energy consumption, realized fully solid particle being separated from the single flow water source and enter heat transmission equipment again and recycle.
The present invention is achieved by the following technical solutions, mainly is made up of single flow water source pipe network, automatically taking water decontamination apparatus, water pump, single flow water source inlet pipeline, down-comer bottom member, vertical fluid-bed heat exchanger, motorless gravitational settling formula solid-liquid separator, down-comer, overflow passage etc.The water source enters in the automatically taking water decontamination apparatus 2 according to single flow water source inlet pipeline 4, large-scale dirty foreign material are removed, enter vertical fluid-bed heat exchanger 6 through inlet pipeline by water pump 3 again, the single flow water source adds the generation that solid particle comes the strengthening device exchange capability of heat and prevents dirt before entering heat transmission equipment, in the outlet of the single flow water source of vertical fluid-bed heat exchanger 6, motorless gravitational settling formula solid-liquid separator 7 is installed, these solid particles are separated enter heat transmission equipment again according to down-comer 8 and recycle, behind discharging of single flow water source or the absorption heat, return in the single flow water source pipe network 1 by overflow passage 9.
Down-comer bottom member 5 increases flow velocity and reduces fine pressure by the caliber that reduces horizontal pipeline, thereby the particle in the down-comer is brought in the heat exchanger.Enter behind the casing of motorless gravitational settling formula solid-liquid separator 7 static substantially from the single flow water source of vertical fluid-bed heat exchanger 6, solids sedimentation under the self gravitation effect, bottom half adopt the circular cone type mode that solids are deposited in the middle of the down-comer well.
25～60 ° angle is adopted in down-comer and bottom member 5 junctions, so that solids can well enter in the horizontal pipeline.Cause fine pressure to reduce under the acting in conjunction with the hydraulic pressure that liquid level forms of motorless gravitational settling formula solid-liquid separator 7 at down-comer bottom member 5 places, liquid is in suspended state substantially in the down-comer 8, solids rely on the bottom of gravity effect free settling to down-comer 8, and then bring back under the high-velocity flow at down-comer bottom member 5 places in the vertical fluid-bed heat exchanger 6.The screen pack that the aperture is slightly smaller than the solids diameter is installed at overfall 11 places on the gravitational settling formula solid-liquid separator 7, separate fully to guarantee solids, solids are wear-resistant, intensity is good, be difficult for brokenly, easily adopt density greater than the sand at single flow water source, steel ball, copper ball, polytetrafluoroethylparticle particle, polyformaldehyde particle, glass, pottery etc.
The key technology of single flow water source (rivers water, municipal sewage, lake water, underground water, seawater etc.) Lowlevel thermal energy utilization is the Energy extraction process at single flow water source, i.e. heat exchange property and dirt blockage problem.Compared with former existing technology, the present invention has substantive distinguishing features and obvious improvement, this invention is adopted circulating fluidized bed technique to strengthen heat exchange and is suppressed dirt, in the outlet of the single flow water source of heat transmission equipment, motorless gravitational settling formula solid-liquid separator is installed, this solid-liquid separating method does not consume extra energy, realizes that solid particle is separated to enter heat transmission equipment again according to down-comer and recycle from the single flow water source.
Benefit of the present invention and effect are not increase the extra energy consumption of system, the dirty foreign material that thoroughly solved during single flow water source low level Cooling and Heat Source is utilized stop up heat exchanger and the bad shortcoming of heat exchange property, can be heat pump Cooling and Heat Source is provided, also can be used for the cycling use of water of cooling large-sized equipment.This system can be used for heating, air-conditioning, also can supply domestic water, is suitable in the hotel, occasion uses such as market, office building and villa dwelling house, has tangible environmental benefit, social benefit and economic benefit.
